CVQ Series - Extended Medium Voltage Disc Varistors
General Information
Agency Recognition
The CVQ series of transient surge suppressors is the extended version of CV series disc
shaped varistors. The CVQ series consists of 7 mm, 10 mm, 14 mm, 20 mm and
23 mm sized varistors with extremely high current and energy capabilities. This series
provides an increased level of protection for the transients expected in telecommunication
and AC power networks. The AC operating voltage of these varistors ranges from 60 V
to 550 V.

Assembly Recommendations for Through-Hole Components
Very often before soldering through-hole components, their leads
get bent. It is important not to damage the components during lead
bending. Damage incurred during bending is cracks in epoxy parts,
which can lead to increased humidity sensitivity of a component and,
consequentially, a shorter lifetime.
POINT TO BE FIXED
2
(.079)
In order to avoid epoxy damage, it is necessary to:
- fix the most sensitive point (epoxy parts) of a component body
- bend the wire at least 2 mm below the end of epoxy parts
DIMENSIONS:
Other potential damage to a component which can lead to component
failure or a shorter lifetime is thermal shock during manual soldering
with a soldering iron. This can occur when a soldering iron is placed
too close to one point of the component body and it happens most
often when the solder joint is too close to the varistor body.
MM
(INCHES)
Resistance to Soldering Heat
In the case of automatic wave soldering, it is important to provide sufficient resistance to soldering heat. In order to prevent any
potential problems, internal standards were introduced for testing the resistance to soldering heat of through-hole components: 300 °C,
10 seconds.
Pb-free Wave Soldering Profile Recommendations
Recommended soldering profiles for all above components are in accordance with JEDEC standard curves (J-STD-020D) and are,
therefore, compatible with the Pb-free process.
